To all whom. it m ag concern I l 3 Be it known that I, Gnonen; 1V. CARR, a

citizen of the United States of America, residing at theoity of St. Louis, State of Missouri, have invented a certain new and useclutch member 24 surrounds one "end of the so ful RailwaysCar, of which the following is shaft 20 and is provided witha concave resuch a full, clear, and exact description as oess 25 bearing against a convex washer 26 will enable any/one skilled in the. art to which also surrounds the shaft 20 and bears which it appertains to make and use the againstv the disk 21. This bearing, together same, reference being hadto the aecompanywith the fact that the pins 23 fit loosely in ing drawings, forming part of this speoificathe openings 22, allows of a certain amount 7 tion. i of pivotalmovement between the clutch My invention relates to, a railway ear, member 24 and'the disk 21, or, in other and, more particularly, to that class of cars words, a flexible connection is secured bewhich is adapted to run upon an elevated tween these parts. Cooperating with the track and to be controlled by means exterior clutch member 24 is a second clutch member to the car itself. 1 o v 28 which is provided with a roller bearing In the accompanying drawings, which which cooperates with a ball 30 formed illustrate a'portion of a railway car emon the reduced end 31 of the shaft 20.

Keyed to this shaft 20 is a disk 21, end of the car into operative position, and shown in detail in Fig. 8. This disk 21 is that at theother end of the car out of opera} provided with openings 22 to receive pins 23 l carried by a hollow member 24forming one port on of the clutch mechanism, for connecting the shaft 13 with the motor16L-This tive position, the car will ,be driven in one direction, while by reversing the clutches, the car will be driven in the other direction.

In order to provide'braking means for the car, 'a pinion 46 engages wlth the bevel gear wheel 48 ata point opposite to the pinion 19 hereinb'efore described. This pinion 46 is secured to the end of a shaft 47, the opposite end ofwhich is supported by a bracket 48 carried by the truck frame 10. Mounted frame 10. In order to apply the brake, it

is necessary to move the non-rotary portion '50 longitudinally. To accomplish this, I

provide a sleeve 53 between which and the member 50 is a coil spring 54. This spring 54 is engaged by a yoke 55 carried by a lever 56. This lever 56 is pivoted at 57 to the truck frame 10, asbest shown in Fig. 3 of the drawings. The opposite end of the lever 56 has a slotted connection with one arm 59 of a bell crank lever. The' opposite arm 60 of this bell crank lever is provided with a downwardly projecting roller 61. The bell crank lever is carried by means of a bracket 62' bolted to the truck frame 10, as best shown in Fig. 4 of the drawings. The roller 61 carried by the arm 60 of the bell crank lever is adaptedto come into contact withthe cam track 63 so as to apply the brakeat any suitablepoint, as, for instance,-at the top of a grade. In order to hold the brake in applied position, theend of the arm 60 is provided with a boss 64 having a recess adapted to be engaged by a locking'pin 65 carried in a bracket 66 secured to the truck frame 10. This locking pin 65 is normally moved downwardly by means of a coil spring 67. It will be evident that after the recess in boss-64 is engaged by pin 65, the brake will be held in applied position. In order to release the brake at any suitable point, as, for instance, at the bottom of a grade, the locking pinion is provided with a laterally projecting rod 69 which is adapted to be engaged by a cam track 70, shown in detail in Fig. 6 and moving upwardly so as to release the brake.

is a frame forming the lower ortion of the car body. This body frame 7 5 is sup ported above the truck frame 10 by means ofcoil springs 76 which enter pockets 77 in the upper portion 12 of the casings hereinbefore referred to. In order to guide the body frame 75 in its up and down movement, I provide guide pieces 77, referably one at each side of the springs 76, as best shown in Fig. 1 of the'drawings. These guides 77 are secured tothe body frame 75 and make sliding contact with the inner faces of the truck frame 10. Each of the guides 77 is provided with an over-turned portion 7 8,' as best shown in Fig. 2. These over-turned best shown in Fig. 1, so as to make sliding contact with the edges of the guides 77.

The operation of my car will be evident from the above description. WVhen the car is to be started out upon a trip, one of the levers 43 is moved so as to throw its clutch into operative position, whilethe other of said levers is moved into position to throw its clutch out of operative position. In this manner, the'car' can be run in either direction desired. The connection'between the motor 16 and the driving wheels is such that the clutches may be properly'applied, no matter whether the various portions of the shaft are in" perfect alinement or not. This is essential, not only because it is difficult to secure perfect alinement'in' the first instance, but also because the slight cambering of the car under varying load would disturb the alinement when not properly secured.

As has been above described, the brakes are automatically applied and released by means of the cam tracks arranged at proper intervals along the track 15.

Having fully described my invention, what I claim as new and desire to secure by Letters-Patent of the United States is:

1. The combination with a car frame of two sets: of car wheels, a motor, gearing actuated from said motor for driving one set of wheels in one direction, and theother set in the. other direction when the motor is running in the same -direction,.and means for throwing one set of wheels into engagement and the other's'et of wheels out of engagement with themotor.

, 2. The combination with a car frame, of two sets of car wheels, a motor, gearing ac.- tuated by said motor for driving one set of wheels in one direction and the other set in the other direction when the motor is running in the same direction, a clutch mechanism for throwing one set of wheels into and the other set out of engagement with the motor.

3. The combination with a car frame, of a pair of casings secured to said frame, an axle mounted in each of said casings, and provided with car wheels, a bevel gear mounted on each of said axles within the casing, a motor, gearing for, driving said bevel gears from said motor, said gearing being arranged to drive said bevelgears in opposite directions when the motor isfrunning in the same direction, and means for throwing one of said bevel gears into and the other out of operative connection with the motor.

4. The combination with pair of wheels, wheels, a clutch arranged between said m0- tor and wheels for connecting and disconnecting same, and a flexible connection allowing lateral motion interposed between the clutch and motor.

5. The combination with a car frame, of a pair of wheels, a motor for driving said wheels, a clutch arranged between said motor and wheels for connecting and disconnecting the same, a flexible connection interposed between the clutch and wheels, and a second flexible connection interposed between the clutchand motor.

6. The combination with a car frame, of a pair of wheels, a motor having its shaft arranged longitudinally of the car, gearing for driving said wheels from said motor, a clutch mechanism for throwing said gearing into and out of'operative connection with the motor, a pair of disks, one secured to said shaft, and pin connections bea car frame, of a a motor for driving said tween said disks, said connections being arshaft extending longitudinally of the car, a

divided shaft for driving said wheels from said motor, a pair of disks each connected to one part of said shaft, pin connections between said disks, a clutch mechanism, a third disk carried by said shaft, and pin connections between said third disk and one pair of said clutch mechanisms.

8. The combination with a driving member, of a driven member, a longitudinal ex tending shaft communicating power from said driving member to said driven member, said shaft including two end portions and a central portion, said central and end portions having ball connections, and disks carried by said portions and having pin connections with each other.

In testimony whereof, I have hereunto set my hand and aflixed my seal in the presence of the two subscribing witnesses.
